Description

  The present invention relates to a simple house frame connecting bracket used for a simple house frame, such as a vinyl house or a prefab, which is assembled by connecting pipes, and in particular, three or more pipes intersect. The present invention relates to a framework connecting bracket for a simple house used in a connecting portion.

  In general, in a simple house such as a plastic house or a prefab, for example, as shown in FIG. 11, a metal pipe P such as steel is connected to construct a framework T, and then a resin sheet is attached to the framework T. It is constructed by covering or attaching plywood.

As the connecting portion J, for example, a one-way pipe P (A1) that constitutes the top (ridge) of the roof, and a pair of other-direction pipes P (B1, B2) that constitute the roof wife and follow the inclination of the roof, There is a top end portion J (a1) of the roof where the other direction pipe P (B3) of the vertical beam that is erected on the pipe P (B4) of the horizontal beam that constitutes the wife of the roof intersects.
In addition, as another example of the connecting portion J, for example, a one-way pipe P (A2) that constitutes the bottom edge of the roof and a one-way pipe P (B1) that constitutes the wife of the roof and follows the inclination of the roof. Or B2), the other direction pipe P (B4) of the horizontal beam that forms the roof wife, and the other direction pipe P (B5) that rises from the base (ground) and forms the column intersects the bottom edge J of the roof There is (a2).
Furthermore, as another example of the connecting portion J, for example, there is a one-way pipe P (A2) that constitutes the bottom edge of the roof and an other-direction pipe P (B6) that rises from the base (ground) and constitutes a pillar. There is a skirt edge middle portion J (b1) of the roof that intersects at right angles.
Furthermore, as another example of the connecting portion J, for example, a one-way pipe P (A2) constituting the bottom edge of the roof and a one-way pipe P (A2) extending from the other-direction pipe P (B7) of the column. There is a skirt edge middle portion J (b2) of the roof where the other-direction pipe P (B8) constituting the reinforcing material laid on the crossing at an acute angle (or an obtuse angle).

  Conventionally, in the connecting portion J of the framework T of such a simple house, for example, the pipe P is bound with a wire material such as a wire, or a pipe for a scaffold used for construction work or the like. A clamper or the like for connecting P is used.

As a scaffold clamper, for example, a double clamper that connects two orthogonal pipes as described in JP-A-2002-295417 (Patent Document 1) is known.
Further, a triple clamper as described in Japanese Patent Laid-Open No. 2001-262824 (Patent Document 2) is also known. As shown in FIG. 12, there are two unidirectional pipes P (A) and two unidirectional pipes P (A) arranged with an axis perpendicular to the axial direction of the unidirectional pipe P (A). And three clampers 100, 101, 103 that clamp each pipe P, and a plate 104 to which each clamper 100, 101, 103 is fixed. ing. A clamper 100 that clamps the one-way pipe P (A) and one clamper 101 that clamps the other-direction pipe P (B) are fixed to the plate 104, and the other clamps the other-direction pipe P (B). The clamper 103 is movable with respect to the plate 104 so that the angle can be adjusted.

JP 2002-295417 A JP 2001-262824 A

By the way, in the conventional double clamper, since it is for two pipes orthogonal to each other, it can be used in the hem edge intermediate portion J (b1), but as in the hem edge intermediate portion J (b2) as described above. When the angle of the axis of the pipe P is smaller (or larger) than 90 degrees, there is a problem that this cannot be used. In addition, when three or more pipes P intersect, a plurality of pipes P are used, and in some cases, a wire is also used. However, the pipes P are overlapped and the connecting portion becomes complicated, and the subsequent mounting of the exterior material is performed. There is a problem that it is difficult and the appearance quality is impaired.
In the triple clamper shown in FIG. 11, the other clamper 103 that clamps the other-direction pipe P (B) is movable to the plate 104 so that the angle can be adjusted, but the other-direction pipe P (B ) Is fixed to the plate 104, the degree of freedom of angle adjustment is small, and it is difficult to cope with a complicated angle relationship between pipes, such as the connecting part of the frame of a simple house. There was a problem. In addition, when four or more pipes P intersect, a plurality of pipes P are used, and in some cases, a wire is also used. However, the pipes P are overlapped and the connecting portion becomes complicated, and the subsequent mounting of the exterior material is performed. There is a problem that it is difficult and the appearance quality is impaired.

  The present invention has been made in view of the above problems, and increases the degree of freedom in adjusting the angle of the clamper, thereby facilitating the connection of the pipe of the connection part and simplifying the structure of the connection part. An object of the present invention is to provide a simple house framing fitting that allows easy mounting of an exterior material and improves appearance quality.

In order to solve the above-mentioned problem, the frame connecting bracket for a simple house according to the present invention is a frame connecting portion of a simple house assembled by connecting pipes to one unidirectional pipe and an axis of the unidirectional pipe. Used in a connecting portion where at least two or more other direction pipes arranged with an axis on one orthogonal plane intersect, and each pipe is rotatably provided on the fixed piece and the fixed piece.

The plate is configured to include a secondary clamper mounting portion to which the secondary clamper mounting portion is detachably mounted so that the axial direction of the second-direction pipe clamped by the secondary clamper is variable.

  Thus, when connecting the pipes, the attached portion of the secondary clamper is attached to the secondary clamper attachment portion of the plate corresponding to the other direction pipe in the plate on which the main clamper is integrally fixed in advance. At this time, the angular position of the secondary clamper mounting portion is selected according to the inclination of the other-direction pipe, and the secondary clamper is fixed to the plate. In this case, the angle can be adjusted simply by changing the fixing position of the sub clamper in accordance with the inclination of the pipe in the other direction, so that the operation is performed very easily. Further, since the fixing position of each sub clamper can be changed, the degree of freedom in adjusting the angle of the clamper is increased. In this respect as well, the operation can be performed very easily.

Then, the connecting fitting is positioned at the connecting portion, and a pipe corresponding to each clamper is inserted and clamped. In this case, since the pipes can be connected by simply clamping the pipes to the clamper, the operation can be performed very easily.
In this way, in a state where the pipe is attached to the connecting metal fitting, the other-direction pipe is disposed with the axis on one plane orthogonal to the axis of the one-way pipe. It is possible to prevent the overlapping of the connecting part from being complicated, thereby simplifying the structure of the connecting part, facilitating the subsequent mounting of the exterior material, and greatly improving the appearance quality. Can be improved.
In addition, when a pipe is further incorporated into the pipe structure once assembled using the connection fitting, the pipe can be joined using the connection fitting of the present invention. In this case, in each clamper, the fixed piece of the clamp part is fixed to the plate in advance in the main clamper, and the fixed piece of the clamp part is fixed to the plate through the attached part in the secondary clamper, so that the movable piece is free. Therefore, the movable piece can be easily attached to the pipe structure once assembled by rotating it, and the versatility increases accordingly.

The structure is formed so as to be variable in the predetermined angle range. Since the angle can be adjusted without taking the axis of the unidirectional pipe as the center, it becomes possible to connect four or more pipes at various locations, and the versatility can be further improved.
